Re: Email blacklist

I create reports via SAS every night and then send an email from the
mainframe to several techies and managers to tell them the reports are
available for review. I've never run into anything like this yet. Then
again my company might not be checking the same services yours does.

Subject: Email blacklist

A few nights ago we started getting this message when we tried to send
emails from the mainframe to our Outlook email server:

EZA5198I 03/25/08 23:25:23 2< 550 Denied by policy: Sender is listed
on
DNS-based RBL.

The Outlook admin explained that we use several outside services to
identify email from SPAM sites and, for whatever reason, one of those
sites had identified the mainframe's IP as a SPAM'er. He said we
should
also be getting a message or email identifying the IP address of the
service that had blacklisted us. The problem cleared by itself,
presumably when the service corrected the problem, but I have not been
able to find anything in the Communications Server manuals that talks
about this. Has anyone else had the honor of being blacklisted and,
if
so, did they receive anything to tell them who had blacklisted them?

Thanks,
